Homework Answers
• 10.31 – Constant T so Pvap is constant at 28.0 mm Hg
• 10.47 – a) melting, b) no change, still liquid
• 10.49 – boils when Patm gets down to Pvap
• 10.51 – 36.6 kJ released• 10.53 – 26.9 kJ released• 10.55 – • 10.57 – 7.12 J/(K∙mole)• 10.119 – BP = 77˚C,
Pvap = 58.9 mm Hg

Probing the Structure of Solids: X-Ray CrystallographyDiffraction: Occurs when electromagnetic radiation is scattered by an object containing regularly spaced lines (such as a diffraction grating) or points (such as the atoms in a crystal).
Interference: Occurs when two waves pass through the same region of space.
